Gilbert mass shooting: Members of extended family were targeted

The four victims and sole survivor of Wednesday's shooting were members of an extended Gilbert family. Here is information about them piece together from family, friends and court records:

Lisa Lynn Mederos, 47, had been seeing J.T. Ready for about two years, according to Mederos' ex-husband, Hugo, an airline mechanic who now lives in Tampa. Lisa was a homemaker, and Hugo still paid spousal support, and she and Ready lived in a house owned by Hugo. Hugo said he had no idea of what went on in the house or their relationship. He had only met Ready once, but he said that Lisa had a lot of friends and was a good mother to her two daughters. One of Lisa's neighbors said that she was a stay-at-home grandmother with baby Lilly.

Amber Nieve Mederos, 23, worked at a Wendy's restaurant in Mesa, and had just interviewed for a managerial position there the day before she was killed. She graduated from Gilbert's Mesquite High School in 2008 and was in the color guard there. She was also working to get a job there for her fiance, Jim "Jambob" Hiott. She loved everything about Disney, her father said, and planned to move to the Orlando area when she realized her goal of going into a medical field. Paperwork for J.T. Ready's exploratory committee to run for Pinal County Sheriff listed Amber as the committee treasurer in January, but her name was removed when amended papers were filed in March. Her last Facebook post was "Time to get the drama out of (m)y life and make a better life for me my daugher and my love."

Lilly. Amber's baby Lilly was 16 months old, and "just learning to run," according to her grandfather, Hugo Mederos. She was the child of Jess Boggs, who declined to discuss the killings, saying, "I just lost my daughter." The child appears in numerous photos on family Facebook pages.

Jim Hiott, 24, came from Waterboro, S.C., and had served in Iraq with the National Guard. On his Facebook page, Hiott, who went by the nickname "Jambob," described himself as "just a white boy who is trying to make it in life." He and Amber shared an apartment in Mesa, and Amber was trying to help him find a job. A close family friend said that he met Amber online and then moved to Arizona. "He was willing to help you do whatever he could," the old friend said, an opinion seconded by Hugo Mederos. "He was a great guy and he took care of my daughter," Hugo said.

Brittany Hazel Mederos, 19, who survived the shootings, had already suffered trauma when she was nearly killed after she and her mother were run down accidentally by a car in 2008. She lived in the house with her mother and Ready. She was in a bedroom when she heard the shooting and found the bodies. Then, according to Hugo Mederos, she ran to a neighbor's. "In the end, you know, everybody's dead," Hugo said.
